I don't think that it's a f2p thing inherantly. We just got a rush of new players at once. I'm sure a few of them haven't played an mmo before either. Just give them time to learn their class, how how the different war zones work.

I remember when I started playing I had no idea that there was a pass the ball skill for Hutt Ball, and when my shadow got her first taunt I wondered why the hell anyone would want to use that. Didn't figure out what a healer and tank were really for until I had an epiphany on Alderaan. xD
